In Figs. 3 and 5 X-X and Y-Y are the two series of parallel wires whichare interlaced to form the trellis work while in Figs. 4 and 6, aa arethe ornamental undulations and 6-?) are the undulations at the crossingpoints for producing a flat weave.

The machine illustrated in Figs. 1, 2 and 7 comprises two pairs ofdiscs, rollers or cylinders A--B, C-D, The rollers A and B have parallelaxes and are situated in a vertical plane, the rollers C and D also haveparallel axes and are arranged in a horizontal plane. The rollers A andB engage and the rollers C and D also engage and are arranged in such away that the wire, leaving the rollers AB is caught by the rollers C andD. That which has been called engaging is not an engagement in themechanical sense of the word. It is here simply intended to mean thatupon the said discs (or rollers) are set a series of teeth in such a waythat a projection of A or 0 corresponds with recess on B or Drespectively, and that sufficient space is left between them for thepassage of the wire which is thus undulated.

In Figs. 8 and 9 a part of these rollers is shown in detail. They are ofcast iron machine turned, and upon their peripheries are set theprojections or teeth a, b, 0, d which are members of suitable form madeof tempered steel and spaced the required distances apart.

From a consideration of the machine and i of its work, it will be seenthat the applicant has designed the former so that it will produce thisdesired efiect of preventing the interposed series of undulations fromadvancing relatively to the others. For this purpose the main or drivingshaft E which receives the power, is arranged to drive by means of aworm, the worm wheel F upon the shaft of which is mounted the cylinderor disc B; by means of the similar toothed wheels H and J, its movementis transmitted to the shaft K, upon which is mounted the disc A whichco-operates with the disc B, and by means of the system of helicalwheels L and M drives the shaft N which through another helical system0-]? drives the shaft Q, upon which is mounted the disc D and also thespur wheel It which engages with another wheel S similar to itself uponthe shaft T of which is mounted the disc C.

In this way the same distance is preserved between each consecutive pairof undula-' tions.

The whole arrangement is mounted upon a rigid bed U, one form of whichis indicated in the figures, upon which are mounted the bearing andsupports for these transmissions and discs.

It will be understood that modifications may be made in theconstructional details without on that account going outside the scopeof the invention.

What I claim is:

1. A machine for producing ornamental undulations in wire in two planes,situated at an angle to each other, comprising, in a unitaryconstruction, a first pair of co-operating rotatable discs or the likearranged in one plane, between which the wire passes so as to form theundulation in this plane, and a second pair of such discs, separate fromthe first, arranged in the second plane, between which the wire passesafter leaving the first pair, so as to form the undulations in thesecond plane, shafts carrying discs, and means mounting the shafts onone side only of each pair of discs.

2. A machine as claimed in claim 1, char:

acterized by the provision of a drive shaft connected with one of thediscs of the first mentioned pair, and a driving connection between saidshaft and one of the shafts of the discs of the second pair.

In testimony whereof I have signed my name to this specification.
